Also in game: Use wsad to move the red square, and the arrow keys to move the blue square. Don't let the red square touch red, and don't let the blue square touch blue. It will push you down, and if you touch any edge you lose. You can switch between easy and hard mode (and ultra) in the options. Harder modes give more points. You have to click 'Retry' twice before it works.
Code and graphics by JL. Music by Kevin Macleod. This game was intended for single player, but you can easily have 2 people playing at once. Please comment. I love comments. :D Good luck to anyone who tries to beat the highscore! You have to click 'Retry' twice before it works.
